The Impact

The Salado River Basin region is the most important livestock breeding area inArgentina, wherethe Lotus species has been traditionally cultivated as forages.Nearly 60% of their land surface is dominated by salt-affected soils with severeconstraints for crop cultivation. In order to cope with that limitation, farmers haveutilized species such as non-native L. tenuis (ex- Lotus glaber), which shows a verygood adaptation. As a result, inter-seeding of L. tenuis has been proposed as astrategy of choice for improving forage production in marginal areas. The increasein soil quality by these means is achieved by an increment of the organic mattercontent, improvement of soil fertility as well as microbial biodiversity. Thus, theintroduction of L. tenuis and/or other Lotus genotypes could have enormousbenefits for similar constrained lands around the world. We are developing anintegrated analysis of the changes that occur in soils under legume production. Wewill not only analyze the microbial diversity associated, but also soil physical andchemical characteristics and the impact of different legume-microbes associationon mitigation of GHG emissions. In addition, we are identifying the main geneticdeterminants associated with interesting agronomic traits such as plant toleranceagainst biotic and abiotic stresses and the content of condensed tannins. Our futureand present research will build a solid base for the improvement of agronomicallyimportantspecies and the development of better strategies for the management ofconstrained lands such as the lowlands in the Argentinean Pampas.

ABSTRACT A total of 103 root nodule isolates were used to estimate the diversity of bacteria nodulating Lotus tenuis in typical soils of the Salado River Basin. A high level of genetic diversity was revealed by repetitive extragenic palindromic PCR, and 77 isolates with unique genomic fingerprints were further differentiated into two clusters, clusters A and B, after 16S rRNA restriction fragment length polymorphism analysis. Cluster A strains appeared to be related to the genus Mesorhizobium, whereas cluster B was related to the genus Rhizobium. 16S rRNA sequence and phylogenetic analysis further supported the distribution of most of the symbiotic isolates in either Rhizobium or Mesorhizobium: the only exception was isolate BA135, whose 16S rRNA gene was closely related to the 16S rRNA gene of the genus Aminobacter. Most Mesorhizobium-like isolates were closely related to Mesorhizobium amorphae, Mesorhizobium mediterraneum, Mesorhizobium tianshanense, or the broad-host-range strain NZP2037, but surprisingly few isolates grouped with Mesorhizobium loti type strain NZP2213. Rhizobium-like strains were related to Rhizobium gallicum, Rhizobium etli, or Rhizobium tropici, for which Phaseolus vulgaris is a common host. However, no nodC or nifH genes could be amplified from the L. tenuis isolates, suggesting that they have rather divergent symbiosis genes. In contrast, nodC genes from the Mesorhizobium and Aminobacter strains were closely related to nodC genes from narrow-host-range M. loti strains. Likewise, nifH gene sequences were very highly conserved among the Argentinian isolates and reference Lotus rhizobia. The high levels of conservation of the nodC and nifH genes suggest that there was a common origin of the symbiosis genes in narrow-host-range Lotus symbionts, supporting the hypothesis that both intrageneric horizontal gene transfer and intergeneric horizontal gene transfer are important mechanisms for the spread of symbiotic capacity in the Salado River Basin.
